f ERMUTATIONLOCKQ-P To all whom t may Concern.'

Beit known that LJAcoB Rznszn'rd'a citizen of `Poland, resident of North Chicago, county of Lake, and State of Illinois, have invented certain newV and useful-,Iinpro-vements in Permutation-Locks,of Which'the following is a specification. ,y

This invention relates to improvements in locks, and particularly to those of a portable nature known as padlocks," which may further Vbe divided into types calledv keyless, the operation of locking and,v unlocking? being done by the movement of permutative elements.. ,l I,

The principal object of the invention is. to provide'a. lock of the lclass described'with a supplementary securing means whereby additional safety issecured.

This and other like objects'are attained by the novel construction and combination of parts hereafter described and 'shown inV the accompanying drawing, forming a material part of thi's'ydisclosure, and in which- Figure 1 is a side elevational viewV of a lock made in accordance with the'invention.

' Fig. is asimilar side elevational and vertical sectional view taken through the vcenter of the same.

Fig. 3 is a like sectional view, the parts` being shownin another position.

F ig. 4 is a transverse sectional view taken on line 4 4- of Fig. 3. Y

Fig. 5 is a fragment-al transverse sectional view taken on line 5 5 of Fig. 2.

Fig. 6 is a. longitudinal sectional view taken through one of the tumblers, andV Fig. 7 is an end view of the same.

The lock is comprised of a pair of similarlyV shapedl side members 10 and 12, the same being of substantially parallel thickf ness and width, and having rounded ends.

Formed or rigidly attached to one of the side members 10, is a cylindrical bar 14, con-v taining an axial bore 15, in which may be slidably engaged the rod 16, formed with the opposite member 12, and around the base of which is an annular groove 17, receptive of the eXtreme outer end of the bar 14, near the end of which is a transverse passage 18, alinable with a similar drilled opening 19, passing longitudinally through the side element 12, and in which is slidably engaged a spindle. 20, having an extending head 21, the arrangement being such that when the bar 14 has entered the bottom of the recess 17 Specification-of Letters Patent.

innerside of the sideielvementflOis another bar.` 25, containing a longitudinal slot '26, in which is slidably engaged the ward' bar 28 formed lwith theother side memberf12, 'par'-` allvel tothe rod 16, thew'ard' bar 'carrying upfon upper'surface a plurality foi Wards 30, interposed with'spacesBl, eachof .the wards Vbeing "engageablel in appropriate spaces 32, formed inY the'tumblers l83,' all of' which ,arey rfreely rotatable upon the ii-Xed bar 25,l and heldin'place by the vextended projection', formed .at its end, the firstl of the tumblersy 33 having an extending lannulus 36, engaging-in an opening formed 4in theface of the side element 10, concentric to the bar`25, while the last tumbler 33 has an eXtending portion 3S, receivable in an appro-` priately formed annular 'recess 40l in the innerside of vthe side memberl 121 Formed in the topk of the side ,member 12 isy longitudinal slot 4.2,"terminatin'g at the inner'` diameter of theannular-"recess 40,3

which'a'ls'o [has an 'interior slot 43,V and secured tothe spindle 20ne`ar` the head 21, isla hook `detent 44, Vadapted' to slide in the slot 42 as the spindle isV moved downward,

` after .which itymay be turned so that the hookwill engage through the opening or' Y passage 45, within the annular recess 46 formed in the outer tumbler 33, all ofthese tumblers carrying a seriesof numerals 48 upon their exterior, the same being placed relatively to their interior longitudinalslots 34, receptive of the wards.

In operation, the parts having been as-V sembled, and the lock in a closed position as shown in Fig. 1, let it be desired to open the same. This is accomplished by turning `the tumblers 33, so that the selected num- 'bars 16 and 2S are insertedin their appropriate openings, the two sides 10 and 12 pressed together, the spindle 20 pushed down as far as it Will go and partially rotated so as to rengage the hook 44 Within the annular recess 46, and all of the several tumblers turned in such manner as to maintain the Wards 30 Within the annular grooves 32 and the hook 44 Within the recess 46sothat` itvcannot be turned by operating the knob 2l.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent, is.'-`

l. In a lock ofthe class described, the combination with a pair of separable side elements, a cylindrical bar rigidly attached to one of said sideelements, a slotted bar attached to the saine element at the opposite end thereof, a' rod engageable in said'cyliiidrical bar, attached to the other of said side ele ments, a Ward bar carried by the said second side element operablein the mentioned slot, a plurality of Wards formedwith said Ward bar, cylindrical tumblers engageable With said A'Wards encircling said bar, the outermost of said tumblers having an interior annular recess and an opening leading thereto, a spindle movable longitudinally in the second named side element, said spindle being engageable in the mentioned cylindrical bar, and a hook formed with said spindle engageable in the mentioned recess in the outermost tumbler.

2. In a lock of the class described, the combination with a Vpair of separable side elements, a cylindrical bar secured to one of said side elements, said cylindrical bar having a perforation in the outer end, a slotted bar engaged With the saine side element opposite to said cylindrical bar, a rod formed With the second named side element, enterable in said cylindrical bar, a Ward bar carried by said second named side element slidable in said slotted bar, a plurality of tumblers encircling said bar, a spindle slidable longitudinally in said second element, a hook formed with said spindle and means formed with the outermost of said tumblers by means of Which said spindle may be held in operative position or released therefrom. y

In a lock of theclass described, the combination "with a pair of flat side elements, a cylindrical bar formed with one said side elements, said cylindrical bar being cnterable Within an annular recess formed in the opposite side element, a rod formed on the second named side element engageablc Within said cylindrical bar, a bar Vrigidly engaged with the first named side element, said bar being slotted longitudinally, a Ward bar formed With the second named side .element adapted to slide in the menioned slot, a plurality of rotatable tumblers encircling said bar,v said tumblers having recesses engageable With said Wards, a spindle slidable longitudinally in the second named side eleinent','said spindle being adapted to pass through a perforation.

formed in said cylindrical bar, a hook formed with said spindle, an annular recess having Va slot leading thereto formed in the outermost of said tumblers receptive of said hook, and a knob for operating said spindle.

In' testimony whereof I have affixed my signature.
